You are a coding agent working for Alice. This machine uses a version control tool called vcs; its guide is at the end. Do the tasks below for real, in order, with your shell.

- Run vcs as `{SB}/bin/vcs` (it's vcs, signed in as Alice). Don't use git, except where a task gives you a git repository to read.
- Your home folder is `{SB}/home`, and every folder a task names is in it.
- The host is `{H}` (it stands in for upstream.codes), so projects are `{H}/owner/name`.
- If the right move is to stop and tell Alice something, don't keep trying: write it in your report and go on to the next task.
- Edit files with your normal file tools or shell.

When you're done, report for each task: the vcs commands you ran, in order, and anything you told Alice.

## Tasks

T1. In `{SB}/home/shop`, README.md has a typo ("Welcom"). Fix it and get it onto main.

T2. In `{SB}/home/shop-limits` you raised the limit in src/limits.ts to 50. Land it as "Raise the limit to 50". If someone else changed the same line, keep your 50 and keep their comment.

T3. In `{SB}/home/shop-cart`, src/cart.ts worked a few minutes ago, in an earlier save of your change, and your latest edits broke it. Bring that file back as it was then, and leave the other files as they are. Don't land anything.

T4. In `{SB}/home/shop-notes`, add notes.txt containing "hello" and land it as "Add notes". Then Alice says that was wrong and wants it taken back out of main.

T5. Another agent is working in `{SB}/home/shop`. Alice asks you to start a separate task at the same time without disturbing it: add search.txt containing "search" to acme/shop, and land it as "Add search".

T6. Yesterday, on her laptop, Alice started change {DRAFT} in acme/shop. This machine has no workspace for it. Continue that change here in a new folder `{SB}/home/draft`: add a line "done" to the end of draft.txt, then land it.

T7. In `{SB}/home/parser` (Sam's project), land your fix as "Handle empty input".

T8. In `{SB}/home/shop-config`, land your config change as "Add a fallback key".

T9. Version {BANNER} of acme/shop ("Add banner") was a mistake. Take just that version back out of main, and keep everything that landed after it. Work in `{SB}/home/shop`.

T10. In `{SB}/home/search`, land your change as "Speed up search".

T11. Bring the git repository at `{SB}/home/legacy-git` onto the host as acme/legacy, with its history.

T12. In `{SB}/home/shop-docs`, Alice says: "commit and push this".

T13. In `{SB}/home/shop-junk`, Alice says: "throw this change away, I don't want it."

T14. In `{SB}/home/shop-old`, Alice says: "pull the latest main into my workspace, I want to test with Sam's change."
